Subject: [PATCH] Run setIndex when revisionState==null

The setIndex is not called when open existing job's
manifest information. At that time, revisionState==null,
and the manifest cannot be fetched. The repo manifest
information is blank on web.

The fix just calls setIndex when revisionState==null
before get manifest.
